Theremin.

Here's someone playing a theremin who's reasonably good.[1]

From the article: "When using AirBending for pitch control, you can lock your gestures to specific musical scales and keys. This ensures every note you play is perfectly in tune with your composition"

Reminds me of the Moog Theremini - that was a fun bit of kit.

Great work but wouldn't the iPhone with the lidar depth sensor be a better device?

Not just a ‘theremin’ — that totally downplays the power of midi. Someone else mentioned the mimu gloves, and I love the idea of a vision based controller - almost everyone has a phone, tablet or laptop with a camera, especially if theyre making music.

I also love that this could blur the lines of music playing and dance.

Great job OP, thanks for sharing.
